Hi

just bought a used ibook G4 from ebay for my sister and was giving it the once-over. did a software update and installed 10.5.3 (no backup first!). It installed ok, but after restarting it just sits on a black screen and goes nowhere. It plays the on chimes and churns the DVD drive, but then nothing.

help!

BTW, the computer didn't come with any installation discs

Did you try resetting the PRAM and the PMU?
